⚡ At a Glance
- • Depth Accuracy: Maintains consistent hole depth across repeated drills
- • Best for: Woodworkers and DIYers who need repeatable hole depths
- • Not ideal for: High-speed industrial metal machining or specialist engineering tasks
A set of five aluminium alloy stop collars that clamp onto the drill bit. Sizes cover 6, 8, 10, 12 and 14 mm and two hex wrenches are included.
Consistent hole depths – thanks to screw shrink crimping
A screw-based clamp compresses around the drill bit shank, and the even-closing mechanism distributes pressure to avoid slippage. User reviews note the screw grips evenly, which reduces the risk of the collar moving during drilling.
Repeatable drilling depth across multiple holes saves time on measuring and re-marking. Reliable clamping reduces the chance of over-drilling and inconsistent joinery.
Workshop-ready durability – with aluminium alloy construction
Aluminium alloy offers a lightweight yet robust form factor with corrosion resistance and heat resistance described in the product details. The material resists common workshop conditions that would degrade lesser metals.
Durable collars stand up to regular use without obvious corrosion or heat damage. Longevity means fewer replacements and steadier performance over time.
Immediate usability – with five collar sizes and included hex wrenches
The pack contains five stop collars sized 6, 8, 10, 12 and 14 mm plus two hex wrenches for tightening. The range covers many common woodworking drill-bit diameters and allows quick swaps on site.
A ready-to-use kit removes the need to source individual collars or tools, letting users set depth stops quickly. Practical for bench work and on-site repairs where speed matters.
